HEAT-DI$TRIBUTING DEVICE.

Specification of Letters Patent. Patented lflay 30, 1922,

Application filed April 19, 1920; Serial No. 374,892.

To all whom it may] concern Be it known that I, ALBERT G. Sonnnnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Heatl)istributing Devices of which the following is a specification.

My present invention relates to heating systems, and more particularly to the type known as the monopipe hot air system, that is, a furnace or heater from which a single large hot-air discharge pipe leads upwardl Y to a sin 'le re ister structure for the I g a distribution of the hotair and which generally receives the cool air returned to the furnace or heater for reheating through another portion of the same register structure. V y

In connection with such a furnace or heater, I have heretofore devisedseveral register structures for improving and rendering more effective the distribution of the hot-air discharged from the hot-air flue of the furnace orheater as well as to provide for the ready return of the cool air to the heating element for the piilrpose of re-heating the same. Among these register struc tures, I might mention those for which I obtained Letters Patent of the United States under date ot February 3, 1920, and respectively numbered 1.329502, 1,329,803 and 1.232980%. It is for the purpose ot increasing the capacity of the plant and the volume oi hot-air discharged from the register structures that I have designed my present device.

When a register structure is to be placed in a position such as against a wall or upon both sides oi a partition wall. so disclosed in my hereinbetore mentioned Letters Patent. the vertical plane or the back of the register is of course parallel with the plane of the wall. and. as this cannot be changed or moved difficulty may be encountered in making the installation owing to the fact that the front of the furnace or heater had to be parallel with the plane of the wall so that slight deviations therefrom meant considerable unnecessary labor and time in erecting the :turnace or heater unless great care was used. In my present structure, I

have so co-related the furnace, the air supply and discharge pipes, and the register structure that much time and labor are saved in the erection of the furnace and the installation of the pipes and register structure, and to accomplish this co-relation of the elements, I have disposed the register structure above the furnace with their axes coinciding or in longitudinal alinement. I am enabled by this construction to assemble the furnace and pipes and then swivel or rotate the register until its vertical plane is parallel with the vertical plane of the wall against which the register is placed. Also I am enabled to dispense with considerable pipe between the floor and the top of the furnace or heater, and to a great extent make use of stock or commercial pipes, boots and boxes in the erection of the entire structure. thereby dispensing with specially formed elements that are expensive to manufacture and to replace. Other objectsand advantages will be obvious to others skilled in the art after an understanding of my invention is had, and I prefer to accomplish these divers objects in substantially the manner hereinafter de scribed and as illustrated in the accompanying drawings that torma'part of this speci fication, in which drawings- Figure 1 is a vertical front elevation of my invention, portions of the walls whereof are broken away and in section to more clearly disclose the structure.

In carrying out my invention anysuitstraps 13 and 14:, respectiv able register structure may be employed for the discharge of the warm air and return of the cool air. prefer, however, to make use of register structures similar to those disclosed in my aforesaid Letters Patent of the United States, and my pending application for Letters Patent of theUnited States, filed May 19, 1919, wherein reticulated walls extend above the level of the floor and partially or wholly surround a two-compartment chamber for hot and cold air. Briefly stated, the register body shown in my present application comprises two short metal plates 10 forming the rear wall that extends forwardly at its vertical end portions to provide imperforate portions 11 of the side walls. Three straps, an upper 12, an intermediate 13 and a bottom 14: are bent to a U-shape contour and have the ends of their parallel arms riveted or otherwise suitably securedto the respective portions of the imperforate plates 11. The upper and intermediate straps 12 and 13 are of a T-shape in cross-section while the lower strap 14 is of L-shape in cross-section and the latter is so positioned thatits lateral flange rests upon the floor or other support for the register. Suitable upper grille 15 is fitted between the lateral flanges of the top and intermediate straps 12 and 13, and a lower grille 16 is correspondingly fitted between the flanges of the lntermediate and bottom The rear edges of the grilles have outwardly extended flanges 17 so that said grilles may be drawn tightly to therstraps by bolts 18 passed through these flanges and through the projecting members of angle pieces 19 secured to the adjacent portions of the imperforata plates 11. A heading 20 having perforations 21 is secured to upper strap 12, andta suitable top or cover 22 is fitted down upon the upper edges of this heading 20. Secured to the upper portions of the front and side walls formed by the foregoing structure is a deflector-23 of inverted substantially pyramidal shape that is disposed withits apex at substantially the 1 upper end longitudinal center thereof and at about the horizontal planeyof the intermediate strap 13, as will be seen in Figures 1 and 2 of the drawings. This deflector 23 is above the of the hot-air passageway or conduit from the furnace whichwill. hereinafter bevdescribed.

Two vertically disposed converging walls 24; extend forwardly towards each other from the opposite corners formed by side plates 11 and rear walls 10 and meet at a point slightly to the rear of the front portions of the lower grille. As seen inFigure 2, the upper edges of these walls terminate in approximately the horizontal plane of intermediate stra 13, while theirlower portions extend a suitable distance below the stated, however,

lower strap 14:, the purpose whereof will shortly be explained. It might be here that said walls 24:, together with rear wall 10, provide the triangular shaped upper portion of the hot-air passageway that is in communication with the hotair conduit leading from the furnace structure below the floor, and said walls 24 also divide the interior of the lower portion of the register into two substantially equal portions, the outer whereof is for cool air.

Each wall 24; has a triangular shaped re cess or depression 25 extending downwardly from its upper edge inorder to receive the edges of twin deflectors 26 of pyramidal shape and having their apices inverted, as seen in Figures 1 and 2, so that they flare outwardly towards the front and side-walls or grilles of the register structure. ownturned flanges 27 are provided upon the upper outer edges of the deflectors 26 so'that they may be hung upon and supported by the front and side portions of the intermediate strap 13, and when thus positioned, these deflectors direct the cool air, passing into the register through the front and sides of the lower grille, downwardly into the cool-air or return passageway to the heater or furnace. From the foregoing, it will be seen the register is open upon its front and both sides, and there is no interference or retarding of the two currents of air because of the fact that the heated air is discharged through the upper grille in an upward and outwardly direction, while the cool air is moving towards the register in substantially a horizontal direction.

Any suitable type of hot-air heater or furnace structure may be employed which has its heating unit enclosed withinthe usual sheet metal casing, but as my invention does not'relate to these elements they have been dispensed with in the accompanying ings. The upper edge of the casing carries a T-section annulus or ring 28 from which a frustro conical shaped bonnet 29 extends inwardly at about a 45 degree angle, a cylindrical pipe 30 is secured to the upper edge of the bonnet so that its axis is in longitudinal alinement with the axis'of the furnace casing. Telescoping with the pipe 30 is a similar pipe 31, as seen in Figures 1 and '2 to permit of adjustment for the varying distances between bonnet 29 and the floor supporting the register as well as to permit of the rotation of pipe 31 and its connected parts independently as will presently be disclosed. An adapter 32- connects'pipe 31 with the lower portion of converging walls 24: and rear wall 10, and in order to do this the'lower edge 32 of the adapter is made round fit pipe 31; its rearportion 32 1s fan-shaped drawof pipe 30, 1

or cylindrical to maining upper portion is parallel with walls 24, or in other words, the upper edge of the adapter 32 is triangular, while its lower edge is round, the sides merging into each other to provide this peculiar shape. A pocket or seat 33 is formed at the upper edge of the adapter by bending the metal down and then up to receive and have the lower edges of one plate of walls 10 and wall 24 se cured thereto, thus providing a hot or warm air passageway from the hot-air chamber within the shell to the hot-air passage way of the register.

Resting upon the flange of annulus 281s a cylindrical wall 34 the upper edge whereof terminates slightly above the horizontal plane of the top of bonnet 29 and 1s provided with a plurality of openings 35 to which cold-air return pipes Figure 6 are connected and lead into the lower portion of the shell. A T-section annulus or ring 36 is mounted upon the upper edge of this wall 34 while a converging wall 37 of some what frustro-conical shape, has its lower cylindrical flange 38 resting upon the lateral member of annulus 36, as illustrated in detail in Figure 5 of the drawings. Another T-section annulus 39 is fitted to the upper edge of wall 37 and is secured thereto by bands 40, substantially in the manner shown in Figure 5. I have, however, shaped annulus 39 to conform to the contour of the lower edge of the register structure,that is substantially rectangular,and the sides of wall 37 merge into each other to conform therewith at their upper edge while retaining their circular or cylindrical shape at the lower edge.

In order to make connection between this conical wall 37 and the lower portion of the register front, side and rear walls, I secured a sheet metal apron 41 to the inside face of the vertical flange of lower strap 14 so that said apron depends therefrom below the floor. A skirting 42 is now cut from sheet metal of a width corresponding with the distance between strap 14 and annulus 39. This skirting is made preferably in two pieces the edges overlapping and has oppositely arranged angle brackets 43 that may be drawn toward each other by clamping bolts 44 passed through the laterally profleeting members thereof. This completes the passageway that conveys the cool air received by the register through the lower grille 16 down between the adapter and skirting, then over the bonnet between the latter and cylindrical wall 34, and discharges the s'ame through the apertures 35 to the return pipes leading down into the furnace shell. In. setting up or assembling the structure of the register is placed on the floor after the proper opening has been made therein, and in building up the furnace shell and superposed structure, walls 34 and 37 may be rotated to aline annulus 39 with apron 41 to be fitted at the same time rotating adapter- 32 with its telescoping wall 31 on the fixed wall. 30 of the hot-air passageway. When properly adjusted, skirting 42 is cut to the proper height and secured in place, thus saving considerable time and labor in assembling the entire structure.

I am aware that divers changes or alterations may be made without departing from the principles herein described, but I do sire it understood that all such modifications are contemplated within the scope of the appended claims. In this connection, I wish to state the drawings and description herein iven are merely typical and I do not limit myself to the precise structure shown and described.
